(57) [Summary] [Structure] Formula R 3 SnYLi [In the formula, R is an alkyl group having 1 to 20 carbon atoms, ~ 20 cycloalkyl, C6-20 aryl and C7-20 aralkyl, wherein Y is a diene homopolymer, a monovinyl aromatic polymer, a diene / monovinyl aromatic random copolymer and a block. Is a divalent polymer group derived from any of the copolymers]. Effect: This elastomer provides a vulcanizable rubber compound with reduced hysteresis. Products such as tires manufactured using low hysteresis elastomer polymers are Low rotation resistance. |
